SmartSDR CAT on SmartLink

Supposedly, SmartSDR CAT works on SmartLink. But not for me. When I am on my home LAN, everything works -- SmartSDR CAT shows "Radio Connected", and DX4Win talks to it with no problems. However, when I am away from home using SmartLink, CAT shows "Radio Not Connected" and, of course, DX4Win can no longer talk to the radio -- it just times out. SmartSDR and the radio work flawlessly, just with no CAT.

SmartSDR v2.0.17, Flex-6500, Windows 10 (latest updates) on all computers. I have completely uninstalled all Flex software and reinstalled it, to no avail.

Oh, Tim, Thank you! I had no idea there was a radio chooser on SmartSDR CAT. After your suggestion, it took only a minute to switch the network to my iPhone hotspot, right-click on CAT, and make it work.

Also at the top right-hand corner of the CAT window where it says radio connected, if you do a right mouse click you can turn off the automatic reconnect so that the chooser always appears. It adds an additional step starting CAT, but it can eliminate the connection confusion.
